I can remove this - I left it there originally because NAS is MIT
licensed, and all contributions are MIT licensed as well.  I spent
quite alot of time on this particular driver, so... Whomever this guy
was, he wasn't allowed to change the licensing after the fact.

I'll just remove that section of the comment block.  If he has a
problem with that, he can contact me and identify his specific changes
so we can remove them.

This is probably the tool used to create the slides.  They also state
that these are 'an unpublished work' which is clearly false.  I've
removed these comment blocks.

We were never provided the document source code by NCD, so these are
original slides that I believe were presented at an X11 conference in
1994.  I've removed these lines.

There is an issue with title.ps though - under the copyright section it also
says 'All rights reserved' (not in a PS comment block).

I think in this case, it would be simpler to remove the entire
title.ps document itself, since it doesn't provide any useful
information anyway.  I will just do that, since I lack any ability to
edit it directly.

I think so.  The original NAS authors at NCD were quite sure they
wanted MIT licensing, like X11.

I've pushed these changes to the new git repo.
